Im happy op that you realize calc and physics are what this world is built on. Imagine 2 worlds, one where people studied calc physics and engineering, and one full of only english and communications majors. The former world would have all the stuff we have today, i phones, german cars, xbox, etc, while in the world with only english and comm majors, people would be living in caves, writing poetry and throwing their shit at eachother for entertainment. I prefer xbox
